Implementing Apriori Algorithm

Hi,

I am implementing Apriori Algorithm and i have a question regarding support
calculation.

All the pseudo-codes and examples i have read state that support counts the appearances of candidates in the set of transactions. But from what i understand this is only good if the candidates have a a relationship of exist/non-exist...

What about when all properties have appearance in all transactions, but the difference is that a value of the property might denote the importance/ non-importance of the property in the transaction?

What is a good way to calculate support when i have that kind of data?

Thanks,
Chris
